Class BufferedImageFilter
- All Implemented Interfaces:
ImageConsumer
,Cloneable
BufferedImageFilter
class subclasses an
ImageFilter
to provide a simple means of
using a single-source/single-destination image operator
(BufferedImageOp
) to filter a BufferedImage
in the Image Producer/Consumer/Observer
paradigm. Examples of these image operators are: ConvolveOp
,
AffineTransformOp
and LookupOp

Constructor Details
-
BufferedImageFilter
Constructs aBufferedImageFilter
with the specified single-source/single-destination operator.- Parameters:
op
- the specifiedBufferedImageOp
to use to filter aBufferedImage
- Throws:
NullPointerException
- if op is null
-
-
Method Details
-
getBufferedImageOp
Returns theBufferedImageOp
.- Returns:
- the operator of this
BufferedImageFilter
.
-
setDimensions
public void setDimensions(int width, int height) Filters the information provided in thesetDimensions
method of theImageConsumer
interface.Note: This method is intended to be called by the
ImageProducer
of theImage
whose pixels are being filtered. Developers using this class to retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.- Specified by:
setDimensions
in interfaceImageConsumer
- Overrides:
setDimensions
in classImageFilter
- Parameters:
width
- the width to which to set the width of thisBufferedImageFilter
height
- the height to which to set the height of thisBufferedImageFilter
- See Also:
-
setColorModel
Filters the information provided in thesetColorModel
method of theImageConsumer
interface.If
model
isnull
, this method clears the currentColorModel
of thisBufferedImageFilter
.Note: This method is intended to be called by the
ImageProducer
of theImage
whose pixels are being filtered. Developers using this class to retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.- Specified by:
setColorModel
in interfaceImageConsumer
- Overrides:
setColorModel
in classImageFilter
- Parameters:
model
- theColorModel
to which to set theColorModel
of thisBufferedImageFilter
- See Also:
-
setPixels
public void setPixels(int x, int y, int w, int h, ColorModel model, byte[] pixels, int off, int scansize) Filters the information provided in thesetPixels
method of theImageConsumer
interface which takes an array of bytes.Note: This method is intended to be called by the
ImageProducer
of theImage
whose pixels are being filtered. Developers using this class to retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.- Specified by:
setPixels
in interfaceImageConsumer
- Overrides:
setPixels
in classImageFilter
- Parameters:
x
- the X coordinate of the upper-left corner of the area of pixels to be sety
- the Y coordinate of the upper-left corner of the area of pixels to be setw
- the width of the area of pixelsh
- the height of the area of pixelsmodel
- the specifiedColorModel
pixels
- the array of pixelsoff
- the offset into thepixels
arrayscansize
- the distance from one row of pixels to the next in thepixels
array- Throws:
IllegalArgumentException
- if width or height are less than zero.- See Also:
-
setPixels
public void setPixels(int x, int y, int w, int h, ColorModel model, int[] pixels, int off, int scansize) Filters the information provided in thesetPixels
method of theImageConsumer
interface which takes an array of integers.Note: This method is intended to be called by the
ImageProducer
of theImage
whose pixels are being filtered. Developers using this class to retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.- Specified by:
setPixels
in interfaceImageConsumer
- Overrides:
setPixels
in classImageFilter
- Parameters:
x
- the X coordinate of the upper-left corner of the area of pixels to be sety
- the Y coordinate of the upper-left corner of the area of pixels to be setw
- the width of the area of pixelsh
- the height of the area of pixelsmodel
- the specifiedColorModel
pixels
- the array of pixelsoff
- the offset into thepixels
arrayscansize
- the distance from one row of pixels to the next in thepixels
array- Throws:
IllegalArgumentException
- if width or height are less than zero.- See Also:
-
imageComplete
public void imageComplete(int status) Filters the information provided in theimageComplete
method of theImageConsumer
interface.Note: This method is intended to be called by the
ImageProducer
of theImage
whose pixels are being filtered. Developers using this class to retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.- Specified by:
imageComplete
in interfaceImageConsumer
- Overrides:
imageComplete
in classImageFilter
- Parameters:
status
- the status of image loading- Throws:
ImagingOpException
- if there was a problem calling the filter method of theBufferedImageOp
associated with this instance.- See Also:
